Patch Antenna Array With Honeycomb Substrate for Microwave Wireless Power Transmission Applications

In this study, a patch antenna with a honeycomb substrate is realized using 3D printing technology to reduce substrate loss and improve antenna gain and efficiency. Based on this honeycomb substrate antenna, honeycomb substrate 2 × 2 and 4 × 5 antenna arrays are implemented. The antenna arrays are set respectively as the transmitting and receiving antenna of the microwave wireless power transmission system and complete wireless power transmission tests under different distances. The results show that the improvement of antenna gain significantly improves the efficiency of wireless power transmission. It is also observed that when the antenna array is applied to the transmitting antenna, the power transmission is more efficient than when it is applied to the receiving antenna.
